(c1. I:v2- 118) 3 Claims. l

With the constantly increasing cost of labor in j which above all does not require any preliminary preparation of the furring laths.

In the accompanying drawingthe simpleconstruction ofthe tie and its use is shown.

Fig. lis a longitudinal section of the tie,

Fig. 2 a horizontal projection,

Fig. 3 a vertical cross-section of a poured concrete wall with ties imbedded during the pouring process.

Fig. 4 is a cross section and partial perspective view of a concrete wall, with ties and horizontal furring in place.

Fig. 5 is a vertical orthogonal View, and

Fig. 6 a horizontal section of a concrete wall with vertical furring and ties in place.

Fig. '7 is a partial cross section of a wall built of concrete blocks, and

Fig. 8 and Fig. 9 the longitudinal sections of two modifications of the tie.

According to Fig. 1 and Fig. 2 of the drawing the tie consists of a pliable band of sheetmetal folded around the edge 3 into two superimposed arms I and 2, forming the part of the tie, which is to be imbedded in the wall, serving as an anchor oi the tie.

The length of the anchoring part is somewhat less than the thickness of the wall, from edge 3 to edge 4,

The arms I and 2 of the anchoring part are rmly joined together by one or more punchholes 5 through both arms and by crimping the edges of these holes 6 and 'I into two concentric rings.

The thickness of the Wall will determine the number of the punch-holes and crimped-up rings.

If more than one such hole is used in the tie the direction of the punching and of the crimping is chosen alternatingly from one side and then from the other, as shown in Figs. 1 and 2, thus making the joint between the arms of the anchor much stronger.

The uneven edges of the crimped rings, will hold better in the cement or concrete and furthermore the punch-holes will allow the concrete or cement material to connect quite intimately on both sides of the tie, thus increasing the resistance of the tie against the forces, which will tend to pull it out of the construction.

Beyond the last punch-hole the two arms I and `respective fur-ring strips.

2 2 of the tie remain free from eachother formingthe arms -II and 22 respectively, so thatthey might be spread apart, bent and nailed to their For this purpose they are provided Vwith rholes forthe nails on adequate plates 8.

Fig. 1 shows that these twofree-arms I'I and22 are bent in a right angle .to 'the anchoring part, then each of them folded'into two or .more plies and the Whole package wrapped in paper 23 or some other material which will prevent a bonding between the metal of the tie and the material of the wall,

The paper wrapping might be held either by some glue or twine around the edge 4 of the tie.

The tie as hitherto described is intended for the use in concrete walls, which are poured on place.

Fig. 3 shows a partial vertical cross-section of such a concrete wall, to which horizontal furring shall be applied, in which II] represents the form boards and I2 the stops or supporter beams.

As shown the anchoring part of the tie is placed horizontally in the desired heights of the wall, with the packaged part in a vertical position, touching the inner surface of the form boards, respectively the outer surface of the wall that is to be erected and furred.

After the necessary setting of the concrete and after removal of the forms the packaged parts of the ties will appear on the outer surface of the wall in nest-recesses I3.

The wrapping paper having prevented a bond between the metal of the tie and the concrete material, the packaged parts of the ties can be pried out of the recesses, the wrapping paper torn down and the ties used as intended to x the position of two furring laths in two adjacent rows.

Fig. 4 shows at the same time a preferred solution for the fastening of horizontal laths, namely the tie is placed with its free arm I I immediately under the furring lath I4 in this height, bent and nailed on the same with nail I5, while the arm 22 is turned down to the furring lath in the immediate row below serving as a suspension of the laths in this row.

It shall be noted that the ties are applied in a vertically staggered position so as to avoid crowding of the nails on the furring laths and their consequent splitting.

The tie is equally useful for the fastening of vertical furring laths I8 in which case as shown in Figs. 5 and 6, the packaged part of the ties are to be placed in a horizontal position, so that the 3 arms I I and 22 can be spread in horizontal direction to the right and the left and nailed to the furring strips on both sides.

By omitting the packaging and folding of the free arms II and 22 a form of the tie is attained which can be used in all kinds of walls built of smaller units, as concrete blocks, stones, brick, etc., by placing the anchor of the tie in the cement mortar joints of such walls.

Fig. '7 a cross-section, shows the application of the tie in a wall built of concrete blocks I6.

As the erection of the wall progresses the tie is placed in the horizontal mortar joints II, the anchoring part imbedded and the two extending parts remain free beyond the surface of the wall.

After the necessary setting of the construction the furring laths I4 can be placed. The upper arm I I of the tie is used as a support upon which a furring lath is directly placed, while the lower arm 22 is bent down and nailed to the furring lath in the row below serving as a suspension of the latter.

The above described tie represents a preferred solution of my invention and it is obvious that many Variations in detail are possible within the scope of the invention.

In Fig. 8 is shown a modification, in which the two folded arms I and 2 of the anchor are rmly joined by rivets I9 instead with punch-holes.

In Fig. 9 another modification is shown whererate bands of sheet metal, superimposed and joined by rivets I9.

What I claim is:

1. A metal tie adapted to be cast in a monolithic concrete wall comprising superposed strips of flexible metal joined together along a portion 0f the length thereof, the unjoined portion being bent atv right angles thereto and encased in a material inhibiting bonding with the concrete in which the tie is cast.

2. A device of the kind described in claim 1 in which the ends of the arms have portions folded upon themselves.

3. A device of the kind described in claim 1 wherein the strips are fashioned of an integral length of metal folded upon itself.
